WILLIAM G. CHIPLEY, OF NEW ORLEANS, LOUISIANA, ASSIGNOR TO PNEUMATIC RIM & TIRE COMPANY, OF WILMINGTON, DELAIVARE, A CORPORATION OF DELAWARE.

TIRE.

l Application filed April 10, 1911.

Specification of Letters Patent.

To all whom t may concern:

Be it known that I, WILLIAM Gr. CHIPLEY, a citizen of the United States, residing at New Orleans, in the parish of Orleans and Stat-e of Louisiana, have invented certain new and useful Improvements in Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tires, and particularly to what might be termed semi-pneumatic tires, and has for an object the provision of an improved structure wherein a substantially solid tread portion may be provided and yet the resilient effect of compressed air be utilized to substantially its fullest extent. V

A further object of the invention is the arrangement of a tire having a tread portion, an inflatable portion, and an inflatable neck portion projecting into the first mentioned inflatable portion for guiding the tread portion in its movements so as to permit the tread portion to utilize the resilient effect of the air in the inflatable portion.

A still further object in view is the arrangement in a tire, of a tread portion, an inflatable substantially T-shaped portion merging into the tread portion, and an inflatable retaining portion for fitting a rim, the inflatable portion being connected with and co-acting with the inflatable T-shaped portion in such a manner as to permit the same to project int-o the retaining inflatable portion.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a fragmentary perspective view of an embodiment of the invention. Fig. 2 is a transverse section through a tire embodying the invention. Fig. 3 is a side view of the structure shown in Fig. 2.

In constructing a tire embodying the invention it is aimed to provide a tire which will not puncture by reason of the fact that the body or tread portion is made substantially solid, and therefore cannot puncture, but constructing the same so as to co-act with a pneumatic inflatable portion in order to give a highly resilient effect to the tread portion. To this end the tread portion is formed with a projecting annular neck portion which may be inflated and which merges into an inflatable retaining portion which is adapted to fit into a rim, preferably of the demountable type. This neck portion is designed to guide the tread portion in its movement, and to also help distribute the resilient effect of the air to the tread of the tire, and to normally support the tread of the tire above or out of contact with the rim to which the tire is secured.

In order that the invention may be more clearly understood an embodiment of the same is shown in the accompanying drawings, in which- 1 indicates the spokes of a wheel of any desired kind, and 2 the felly thereof. Mounted on felly2 is a demountable rim 3 which rim is held in place by clamps 4l. Rim 3 is bulgcd at points 5 and 6 and is formed with a neck opening 7 which merges into the upper surface of the rim against which the body portion 8 of the tire rests when eXtreme pressure is brought to bear on the tire. The tire 9 is formed with a tread portion 10 formed preferably of rubber with a few layers of canvas or the like and of such a thickness as to negative any probability of puncturing. The tread portion merges into an inflatable portion 11 which inlatable portion extends downward and forms a neck portion 12 having a projection 13 extending into a retaining inflat-able portion 14. Neck portion 12 merges at points 15 and 16 into inflatable portion la so that the same is substantially one continuous structure in order that the various parts may operate in proper relationship to each other so that the strain on the tread portion 10 will be directed usually in a direct line toward the center of the bottom of the inflatable portion 14, and in this way utilize properly the resiliency of the air in the inflatable portions. The inflatable portion 14 is made to t the rounded or bulgcd portions 5 and 6 so as to resist positively any removal of the tire as long as inflatable portion 14 is inflated. A valve 17 is provided for infiating and dellating portion 14E, while a valve 18 is provided for inflating and deflating portion 11.

In applying or removing the tire both of the inflatable portions are preferably deiated When placed in position, after Which the desired pressure of air is supplied, which pressure may be easily observed or become known by the use of an indicator on the pump Which supplies the air, this forming of course no part ofthe invention.

/Vhat I- claim is:

In a device of the character described, the combination with a rim having an annular groove, of a tire formed with an inflatable portion fitting into said annular groove for holding the tire in place, and an independiatable portion.

In testimony whereof I afiiX my signature 1n presence of tvvo Witnesses.
